PRODUCT OVERVIEW
DESCRIPTION
Beta Calcium Sulfate Hemihydrate, also known as Type III or high-strength Gypsum, is a specific form of calcium sulfate hemihydrate. It is frequently utilized in various dry-mix and pre-packaged bagged products due to its smaller crystal structure and higher reactivity. These properties make Beta Gypsum particularly effective in enhancing the setting, strength, and durability of concrete. It is especially valuable in applications that require high-strength and fast-setting characteristics. In dry-mix concrete, Beta Calcium Sulfate Hemihydrate improves setting, accelerates hardening, and enhances workability. It also helps reduce shrinkage, improves curing properties, and increases the strength and durability of the finished product. This makes it a preferred additive in construction materials where high performance is essential.
